Interesting news for the owners of 135i and 335i models, BMW will offer a performance upgrade for the N54 twin-turbo engine. The press release was issued for the German market, but we expect similar news for the U.S. market as well.

The N54 engine will receive 20 extra ponies, to a total of 326. BMW performance power kit consists of software and hardware components, so we should expect a high performance exhaust as well as technologies that will help the air circulation. Water cooling is part of the kit as well.

BMW 335i Coupé and BMW 335i Cabrio can combine the BMW performance power kit with the seven sport automatic transmission with double clutch.

A BMW 335 equipped with the Performance Power Kit, will accelerate from 0-62mph in only 5.4 seconds. No pricing information at this point, but be prepared to pay for those extra horsepower.

You can read more on where you can see the full press release in German, along with a Google Translate of it.

Thanks for the link Mohammed!

    So why couldn’t they offer it also for a Z4 Sdrive35i, when they already had that upgraded engine in new 7-series?
    Actually i think that they should offer this as a standard for all models with the same engine, atleast for a next model year.

  2. Your welcome Horatiu :)

    I would love to know the price, I think BMW needs to get this right .

    @8er: Very good question. I’m assuming that will capitalize on that in a couple of years, when they can say that the Z4 facelift gets a more powerful engine as well.

    Therefore, sales can be increased

    It’s about time!! So, is this a ZHP option?

    As far as I know, the performance exhaust option is only for acoustics, they give no performance benefit over the standard one. I think the 3’s previous exhaust upgrade included 4-pipe exhausts, 2 for higher rpm resonance and some kind of valve to engage them.

    Wait a minute… what’s this water cooling change? Is it a air-water intercooler?

    BMW is the king of engines, the king of premium cars :)

    And what’s the 535i, chopped liver? Come on BMW.

    The big question is whether this upgrade will be 3x the price and 1/3 the power boost that could be had with an aftermarket flash….

    Priced up for my 335i it was £1300 excluding fitting, absolute ripoff.

    I have just had the performance upgrade fitted to my 335i coupe, it is absolutely blinding!!!, the power increase is immediately noticeable and as as smooth as the origonal car, it has an extra radiator, air intake and upgraded fan as well as a two year extended warranty, not as cheap as an aftermarket re-map but for peace of mind there is no debate. The increase in power, although on paper seems on the low side is well ballanced and the car pulls to 140mph in no time with no tail off of power. In my opinion money well spent and would recomend to anyone.
    Beany’s comment that its an absolute rip off is not valid, the kit you get inc warranty and a car that feels like it has at least 375hp under the bonnet is worth the price.

      Gerard – just having the performance upgrade fitted to my 135i after driving it on a track day – and you’re right – it is absolutely blinding BUT… BMW insurance now say they won’t insure the car! Did you have any trouble? Who are you insured with? Any help/advice would be appreciated.
